SPECIFICATION forming part of Letters Patent No. 734,652, dated July 28, 1903.

" Application filed July 9,1902. Serial No. 114,915. on model.)

To all whom, it may concern:

Be it known that we, CHARLES FREDERIC AINSWORTH, a resident of Lower Brazley,

Horwich, and SYLVANUS ANDERTON, a resident of No. 18 Henry street, Bolton, in the county of Lancaster, England, subjects of the King of Great Britain, have invented certain,

new and useful Improvements inOombing- Machines, of which the following description is aspecification.

Our invention relates to combing-machines for the treatment of fibrous substances of the class well known as of and usually styled the Heilman type, wherein a rotary cylinder carrying combing-needles is mounted to opcrate in contiguity and conjunction with nipping-jaws which retain or hold the fibrous substances while being acted upon by said needles, saidjaws being usually styled the nipper-knife and cushion-plate.

As is well known, the nipper-knife is constructed with a flange called the lip, which projects beyond it to force or carry the fibrous substances into contact with or into the path of motion of the needles on the rotary cylinder for purposes well understood, and it is to the formationand construction of this lip that our invention applies.

In the adjustment or setting of the nipperknife as heretofore constructed it has been found necessary to allow sufficient space between the edge of its lip and the path of motion of the needles points to enable these latter to pass or travel clear of the same withoutactually being brought into contact with it under any circumstances; otherwise said points would be damaged and rendered unfit cient part or portion of a combing-machine to show the application thereto of our invention. Figs. 2 and 3 are frontand back views of a nipper-knife, upon a smaller scale than Fig. 1, constructed in accordance with our invention. Fig. 4 is an end elevation, upon the scale of Fig. 1, of the knife illustrated by Figs. 2 and 3.

In carrying our invention into effect we form the lip a of the nipper-knife Z2 so that we may cover its lower edge with leather cor with other substance of a similar nature that will attain the same result in order that pro- Vided by any means or reason should any of the points of the needles (I on the cylinderf be brought into contact with such substance 0 they will be able to pierce or cut through the same without being damaged or rendered unfit to perform the functions desired of them. Thus we are enabled more closely to press the laps or slivers of fibers passing beneath these lips a down upon or into the paths of motion of the needles (1 without endangering the efficiency of said needles, in this manner greatly increasing the output of the machine.

The method of attaching or securing the leather or other covering 0 over the lower edge knife I) by firmly attaching the lip a, thereto by the screws g, while the other loose end is secured by the strip 11 Instead of covering the lip a with the substance or material suitable for holding the fibers, as well as for being cut through by the points of the needles, as above described, we might make or produce the whole of said detachable lip a of some such suitable substance, as, for example, vulcanite, wood fiber, compressed papier-mach, 0r thelike, and thus attain the object of our invention. However, we preferably make use of the method first before described.

We claim-- 1. A combing-machine having the lip of the nipper-knife extended into close proximity to the path of travel of the combing-needles, the lower edge of the lip being non-metallic to prevent injury to the points of needles that may contact therewith.

2. A combing-machine having; its nipperknife provided With a detachable lip having a non-metallic lower edge extended into close proximity to the path of travel of the combing-needles.

3. A combing-machine having its nipperknife provided with a detachable lip, said lip
